  Although the use of beds has become popular in recent years, the Japanese have a strong attachment to tatami mats. Therefore, in order to satisfy the desire of the tatami mat while simultaneously obtaining the advantages of the tatami mat, a tatami bed having the upper surface of the bed made of tatami is manufactured and sold. The tatami mat has a flat contour that almost matches the plan contour of the bed, but the tatami mat is not suitable for exposure both structurally and externally. A frame is provided, and a tatami mat is laid on the inside. The border frame has a height that matches the upper surface of the tatami mat, similar to the threshold in Japan. In such a tatami bed, a futon or a mat is laid on the tatami room in the same manner as a futon is laid on the tatami room. It can be considered that the insertion portion is used by being inserted between a flat bed upper surface formed by a tatami mat and an edge frame and a futon or mat laid thereon. However, since the tatami surface and the surface of the edge frame made of wood, etc. are slippery for the insertion part of the bed saddle fall-off prevention / elevation assisting device, the above described between the tatami bed and the futon or mat laid on the tatami bed. In the attachment of the device for inserting the insertion portion, the stability of the device is lacking, while the surface of the edge frame made of a tatami mat or wood is easily damaged by the insertion portion made of a metal tube or the like.

  The present invention also has excellent stability when mounted on the tatami bed as described above, and prevents the saddles from falling off the side of the bed without damaging the surface of the edge frame made of tatami and wood. It is an object of the present invention to provide a simple structure that helps a sick person or an elderly person to lift and lower a bed safely and stably.

  In order to solve the above-described problems, the present invention has a front wall portion, a top wall portion, and a rear wall portion so as to be laid over the edge frame of the tatami bed on which a tatami mat is laid. An edge frame straddling portion formed in a U-shape, and a flat tatami mat submerged portion extending to the other end along the lower surface of the tatami, connected to the lower end of the rear wall portion of the edge frame straddling portion at one end And a pair of struts that are supported by the base and extend upward to the upper end and spaced along the bed side edge, and the pair of struts are spaced apart from each other. The distance between the pair of struts is slightly larger than the width of the person's shoulders, and the space between the pair of struts is sized to allow a person to pass. is there.

  In the above-described tatami bed detachment prevention / elevation assisting device, the column portion may be fixed to the front wall portion of the edge frame straddling portion of the base portion at the lower end thereof.

  Moreover, the said base part may consist of a pair of strip | belt-shaped board | plate materials spaced along the bed side edge, and the beam member which connects these mutually in the said edge frame straddle part. In this case, the beam member may be connected to both the edge frame straddle portion and the support column portion on each side at each of both ends thereof.

  The upper end portion of each of the pair of struts may have a structure in which a pipe material is curved in an inverted U shape.

  Alternatively, the upper end portion of each of the pair of strut portions may include a grip portion made of a horizontal short tube material.

  In any of the above cases, the upper end of each of the pair of support columns may be bent toward the lower side of the tatami mat with respect to the lower portion.

  Edge frame straddle formed in a U-shape having a front wall portion, a top wall portion, and a rear wall portion so as to be laid over the edge frame of the tatami bed with tatami mats laid inside the edge frame as described above A base portion having a flat bottom submarine portion that extends to the other end along the lower surface of the tatami mat and is connected to the lower end of the rear wall portion of the edge frame straddling portion at one end, and the lower end by the base portion A pair of struts that are supported and extend upward to the upper end and spaced along the bed side edge, and the distance between the pair of struts is slightly larger than the shoulder width of a person In addition, the tatami bed detachment prevention / elevation assisting device for the tatami bed, in which the gap between the pair of strut portions is sized to pass a person, the base straddles the edge frame of the tatami bed at the edge frame straddling portion, When attached to a tatami bed so as to sink under the tatami mat of the tatami bed, The descending assist device is tightly pressed between the lower surface of the tatami mat and the tatami mounting surface below the tatami mat submerged portion, and at the same time the edge frame and the tatami mat on the rear wall portion of the rim frame straddling portion. It is tightly pressed between the edges and is attached to the tatami bed in a highly stable state. In this way, the corporal dropout prevention / lifting assist device does not deviate when pressed against the tatami mat or the edge frame, and in particular, the tatami mat is in contact with the side edge and the back surface, so that the upper surface of the tatami mat is damaged by the device. Absent. In addition, if the height of the rear wall portion of the edge frame straddling portion is appropriately designed in comparison with the height of the edge frame, the edge frame straddling portion will not be strongly pressed onto the edge frame. It is also avoided that the edge frame is damaged by the portion. The installation of such an anchorage fall prevention / lifting assist device to the tatami bed is done by lifting the tatami edge slightly so that the edge frame straddle of the device lies on the edge frame of the bed, This is accomplished by a simple operation of submerging and lowering the edge of the raised tatami mat.

  If the support column is fixed to the front wall portion of the base frame at the lower end of the support column, the support column and the base unit are joined by welding or the like along the length extending over the entire height of the front wall unit. And the support of the support column by the base can be strengthened.

  The base of the tatami bed for the tatami bed fall prevention and lifting assist device is composed of a pair of belt-like plates separated along the bed side edge and a beam member for connecting them together at the edge frame straddling portion. If so, the base is sufficiently lightweight by a pair of belt-like plate members and a beam member such as a single piece of pipe, but the function of attaching the support to the bed is sufficient even though the base is light and inexpensive. It will be a structure to fulfill. In this case, in particular, if the beam member is connected to both the edge frame straddle portion and the column portion on each side at each of both ends thereof, the beam member, the edge frame straddle portion and the column portion are mutually coupled. In the combined structure of the base portion and the column portion, the strength of the coupling between the two increases, and at the same time, the strength of the interconnection of the pair of belt-like plate members by the beam members also increases.

  When the upper end of each of the pair of struts has a structure in which the pipe material is curved in an inverted U shape, the bed user can first use a tube bent into an inverted U shape with one hand. If you grasp the tube part in front when grasping the upper end of the pillar part, pass both legs between a pair of pillar parts, raise the upper body, and then grab the other pillar part with the other hand until you get off the bed, By sliding the hand that first grasped the tube along the tube bent in an inverted U shape, even if the body direction with respect to the support column is reversed before leaving the bed from lying down, There is no need to change the gripping state of the hand.

  Alternatively, if the upper end portion of each of the pair of support columns is provided with a grip portion made of a horizontal short tube material, the bed user can feel a stable grip by holding the horizontal short tube material with the palm level. Can be obtained.

  Furthermore, when the upper ends of each of the pair of support columns are bent toward the lower side of the tatami mat with respect to the lower portion, the position is displaced from the edge of the bed toward the center of the bed. Support for the arm is obtained.
